The inability of some poeple to absorb milk sugar (hypolactasia) was studied by the authors. Hypolactasia causes many gastrointestinal complaints. Of the 1902 people studied, 18% showed genetically caused adult-type hypolactasia. These people have a down regulation of the lactase enzyme during development (around the age of five.) These people have symptoms of gas, bloating […]

Adult-type hypolactasia (low lactic acid tolerance), an evolutionary phenomenon, is known as lactase non-persistence and primary lactose malabsorption. The lactase enzyme helps metabolize lactose (milk sugar.) Historically, a mutation occurred which prevents that down-regulation of lactase at weaning and lactose digestion persists into adulthood. Not all humans have this mutation. Over 50% of the adult […]
